I am a postdoctoral researcher at the University of Pennsylvania, working with Prof. Rajeev Alur and Prof. Mayur Naik. I obtained my Ph.D. and M.S. degrees from the University of Texas at Austin, where my advisor was Prof. Isil Dillig. Prior to UT-Austin, I obtained my B.E. degree with honors from the University of Science and Technology of China (USTC).

I will be starting as an Assistant Professor in the School of Computing Science at Simon Fraser University in August 2021.

Research Interests

My areas of interest are programming languages, formal methods, and databases. My recent research focuses on helping developers correctly and easily evolve database applications using formal methods. I am also interested in developing foundational program synthesis techniques.

Projects

• Formal Methods for Database Applications

  Developed techniques to help developers correctly and easily evolve database applications during database schema refactoring. Specifically, I worked on verifying equivalence between database programs with different schemas [POPL'18], synthesizing equivalent database programs given a new schema [PLDI'19], and migrating data between different schemas using input-output examples [VLDB'20].

• Program Synthesis and Machine Programming

  Developed foundational program synthesis techniques to automatically generate code from a variety of different high-level specifications, including input-output examples [POPL'17], natural language [OOPSLA'17], logical formulas [OOPSLA'18], and incomplete code snippets [POPL'17, FSE'16].

• Program Analysis for Smart Contracts

  Developed verification techniques for checking workflow and access control properties of smart contracts [VSTTE'19], and utilized this technique to find bugs in real-world Solidity smart contracts.
